~~~ chip molds we know of (possibly even others), maybe it was only used in the chip manufacturing industry and someone's concoction, with or without a name or number possibly due to its controlled, limited use.

I searched even in the time frame of the molds and found nothing except for maybe two styles of lettering with both having the forward slant letter L, and now I can't find either of the two styles which one may have been a convex comedy-type font.
